To ensure that you are not confused, I attached what the experiment was about. I highly recommend you read through it before going to the questions. file:///Users/michaelzheng/Downloads/ExploringEnergy%20(2).pdf Only answer Post lab questions 2-5 For number five, put the answers in the format stated in the background. Thank you.

V. Error Analysis/Questions For the following questions explain what specific error in calculating your Ksp value would occur (i.e. would the Ksp be too HIGH or too LOW), compared to the situation in which no errors occur. When you answer the question, consider how the situation affects the calculation of Ksp. Each answer must have an explanation and type the answer, please. A. The buret was not conditioned (it still had water in it) when you add the HCl. Would the Ksp be too HIGH or too LOW? B. There was Ca(OH)2 solid (that was not filtered off) in your solution to be titrated. Would the Ksp be too HIGH or too LOW? C. You measured 24.00 mL of Ca(OH)2 solution instead of 25.00 mL. Would the Ksp be too HIGH or too LOW? D. The HCl concentration was actually lower than the reported molarity on the bottle. Would the Ksp be too HIGH or too LOW?

Case: 1Sodium chloride is obtained by reacting NaOH with HCl in a batch reactor. NaOH + HCl → NaCl + H₂O Suppose that 100 kg of NaOH and 76 kg of HCL are taken in the batch reactor and 107 kg of NaCl is obtained after some time. Determine: The limiting reactant The percentage of excess reactant The degree of completion (fraction) The percent conversion of NaOH to NaCl The yield (kg of NaCl to kg of HCI) [Bhatt, B. I. & Vora, S. M. (2004)]

Below is a simple set of weights obtained while immersing potato slices in various sugar solutions over 30 minutes. I need help calculating all of this for a 30 min period  a. For each solution, calculate the rate of weight change over this 30-minute period. Show your work in the space below. Once you calculate these rates - fill in the blanks below and then add these answers to your Canvas exam. Write your answer in standard notation and use  3 digits past the decimal point - e.g. 0.005, 0.030. (Note that the last zero in an answer is considered to be a digit). Show your work in the space below.  0.0 M sucrose = _______  _____________ g/min 0.4 M sucrose = _______ ____________ g/min 0.6 M sucrose = ________ ____________ g/min 0.8 M sucrose = ____________________ g/min 1.0 M sucrose = ________   __________ g/min Using the osmosis data in the question above, determine the percent weight change for each sucrose solution and fill in the blanks given below and then add these answers to…

You work in a research organization that is looking for markers of various diseases that can be used as a diagnostic for the disease. It has been reported in the past that high levels of Cu are found in the sweat of people with cystic fibrosis. One of the research projects is focused on looking for high levels of Cu in samples that can be obtained non-invasively such as saliva, sweat, hair, nails, etc. The lab will analyze large samples for Cu. What instrument would you recommend purchasing to support this work, Atomic absorption spectrophotometer or an inductively coupled plasma atomic spectrophotometer? Explain the basis for your decision.
